With these and other obje ts in View my invention consists in lheimproved form and construction of the parts fully described inthespecilicution to follow and the novel fe:

Fig. 4 is a cross section on the line i-2 oi Fig. 3.

Fig. 5 is a. side elevation of the feeding plunger rod removed.

Referring to the drawings:

In its essential features. my improved pencil comprises a barrel 1 toreceive and hold the lead 2, a feeding plunger 3 mo"- able in the barrelin engagement with the lead to feed the same, and a. plunger actuat ingmember 4 sustained by the and and movable longitudinally thereof inengagement with the plunger to advance the same.

The barrel is cylindrimil lori'n with (L bore 5 extending ion duallythere through from end to end. time is of uniform cross-sections] n r'iilgliiOUi; its extent. and is of a diam-n: ."nding l'iSenlr-d Nov. 9.i920.

As :i result the lend willbe solidi held nnd not linble to break when pressure is exerted on theprojecting \vrlting point, as would be :ipt to occur if the lead weregripped at one point only in its length as is the ruse with mun; formsof magazine hein-ils. The forward end of the barrel is Formed with ulon; ilnrlinel slit (5 extending entnel ihrnn zh the same from side toside nnd some iii-stance toward the rear. whereby the lend will he heldwith S]1lll\ fgll[)[)lflg action i lllll'ltlllly t ght to present asolid -wriiing; pnllll free from loos-mess but not loo tight ininterfere with the n'oper fee-ll oi the lend by th feeding: plunger. Inthe present insl'unee the bore of the barrel is oi r. dinnns lrr tozirconnnodute u lead of slen der size at) thut the necessity ofre-sharpenire, the leznl lo present a point sufiiciently line forwriting is molded.

The feeding plunger :3 is in the form of a cylindrical rod or section.of Wire of a diameter to tit snugly in the bore and is of a length toextend at its rear end beyond the rear end ol the barrel as shown inFig. 1. In this noeitii'in the forward end of the plunger engages therear end of the lead, so that when the plunger is advanced by the nmunsnow to he described. the lead Will be pnsitii el w pushed before it andits forward end projected lwyoml the end of the barrel.

The, ydunger actuating member is in the form of a l -:l- "'e e'loswl illits rear end by a head will. S. The sleeve surrounds the rear portion ofthe barrel and the projecting end of the plunger, and is threadedinteriorly as at '9 to engage extermil screw threads ll on the rear endof the barrel, so that by turning the sleeve on the barrel in the properdirection, it will telescope thereon and advance 1011 itudinallythere-oil. The rear end of the p unger rod being' engaged by the endwall of the sleeve, the fed will in this action be forced forwardly bythe sleeve and engaging the lead the latter will. be fed.

The construction described is very simple in form and comprises butthree parts, viz.,

.the barrel. the plunger and the plunger convonivn ly (Elia-toil bygripping tho Hltitvt in the palm oi" the hand and turning the hairrvlwith the thinnh anil linggrr ol' LllL same hand.
